Any unsaved data will be lost.
If you choose to connect to the LIXI Shards Server, then data entered into this form will be submitted to the server. The data submitted will be synchronised between all authors that are connected using the same Package ID. If you connect using a Package ID that has already been used, then the preexisting package data will be loaded in your form. If you choose to not connect, the forms will function locally without sending any data to the server.
